At the rate they're going, they'll out-do BART.
Its not a fair comparison. BART is a mass transit system that serves the highly populated Bay Area. In contrast, the proposed high speed rail system would pass through sparsely populated regions. It won’t have a ridership nowhere near in size to BART. Its a political monstrosity whose sole justification for continued existence is that politicians continue to shovel money down its black hole. BART has been in existence for decades. HSR has no viable customer base, unless you count the politicians lined up in support of it!
